If you need further proof that we, as humans, are travelling back in time to the 1980s, look no further than this latest batch of research from Essex University.
A study by Dr Tuesday Watts has discovered that the difference in length between your index and ring finger could indicate whether you are gay or not.
The study was conducted by measuring the fingers of 18 pairs of identical female twins, where one was straight and the other identified as homosexual.
In conclusion, they found that the gay twin had a more typically 'male hand' than their sisters, which could be a result of testosterone in the womb.
The same experiment was conducted on 14 male twins, where the results were found to be inconclusive.
Dr Watts is quoted as saying by the BBC:
Because identical twins, who share 100% of their genes, can differ in their sexual orientations, factors other than genetics must account for the differences.
Research suggests that our sexuality is determined in the womb and is dependent on the amount of male hormone we are exposed to or the way our individual bodies react to that hormone, with those exposed to higher levels of testosterone being more likely to be bisexual or homosexual.
Because of the link between hormone levels and difference in finger lengths, looking at someone's hands could provide a clue to their sexuality.
While you're probably all measuring your fingers now, we can't help but feel that a person's sexuality comes down to something a lot more profound and complex than the size of their fingers.
Imagine if having a finger bigger than the other means that you should completely determine your sexual orientation and who you are attracted to? Kinda ridiculous when you really sit down and think about it.
Also, the study has a very small research pool and doesn't even accommodate for people who identify as bisexual, pansexual or asexual. Sexuality is a spectrum, after all.
The publications of this study, which has been printed in the Archives of Sexual Behaviour, has created some discourse on Twitter, with most people calling it out for its obvious problems.
